ABSTRACT

Radical prostatectomy (RP) has been found to be curative in most cases of prostate cancer (PCa); however, 20-40% of patients have a biochemical recurrence (BCR) of the disease. Prostatic specific antigen prostate-specific antigen (PSA) levels are used to assess patient prognosis after surgery; however, there is no consensus about the optimal PSA level that defines BCR. Detection of very low volume disease and early detection of the disease are very important predictors for clinical outcomes in BCR, as early salvage radiation therapy (SRT) provides a possibility of a cure. The aim of this study is to review briefly about important and controversies in radiotherapy after radical prostatectomy. No guideline exists to select ideal patients for each treatment, but there are tools currently being developed; genetic tests and prostate-specific membrane antigen (PSMA) positron emission tomography (PET) may be able to identify patients with worse outcomes who would benefit from more treatment.

ABSTRACT

The contribution of chronological age, skeletal age (Fels method) and body size to variance in peak velocity derived from the Carminatti Test was examined in 3 competitive age groups of Brazilian male soccer players: 10-11 years (U-12, n=15), 12-13 years (U-14, n=54) and 14-15 years (U-16, n=23). Body size and soccer-specific aerobic fitness were measured. Body composition was predicted from skinfolds. Analysis of variance and covariance (controlling for chronological age) were used to compare soccer players by age group and by skeletal maturity status within of each age group, respectively. Relative skeletal age (skeletal age minus chronological age), body size, estimated fat-free mass and performance on the Carminatti Test increased significantly with age. Carminatti Test performance did not differ among players of contrasting skeletal maturity status in the 3 age groups. Results of multiple linear regressions indicated fat mass (negative) and chronological age (positive) were significant predictors of peak velocity derived from the Carminatti Test, whereas skeletal age was not a significant predictor. In conclusion, the Carminatti Test appears to be a potentially interesting field protocol to assess intermittent endurance running capacity in youth soccer programs since it is independent of biological maturity status.
